Bimetallic palladium catalysis: Direct observation of Pd(III)–Pd(III) intermediates. Journal of the American Chemical Society 131(47): 17050–17051.0002-78631520-5126http://nrs.harvard.edu/urn-3:HUL.InstRepos:8156526\(PhI(OAc)_2\) is a common oxidant for Pd-catalyzed C−H bond functionalizations. Mechanistic hypotheses since the 1960s have suggested a Pd(II)/Pd(IV) mechanism. Here we present evidence for the relevance of bimetallic Pd(III) complexes to catalysis. A bimetallic Pd(III) acetate was isolated and can afford product by bimetallic reductive elimination.en-UScatalysiskineticspalladiumchemistryJournal Article2012-02-1010.1021/ja906935c
